Device, varieties of insulated metal entrance doors. Insulated entrance doors for a private house Additional elements to ensure protection

What are the basic requirements for entrance doors? First, they must be durable and insulated. There are several features of the choice of such products. Usually, many apartment owners buy entrance doors, based on a good promotional offer, or a favorable price. Also, some are attracted by the beautiful external design of the product. However, if the front door a private house is selected according to these criteria, only big problems can be purchased.

Before going to the store, you should figure out which entrance doors have a lot of advantages, how best to install them, what selection rules to rely on. This will help to buy a quality product that will protect the home from the effects of the external environment and the penetration of uninvited guests. The article presents a lot of photos of entrance doors for a private house.

Types of doors

Metal-plastic and metal structures are very popular. They deserve attention because they have many advantages. Wooden doors are usually not used. This is due to their low fire safety. Also, they do not differ in high strength characteristics.

Most often, apartment owners face the following problems:

the appearance of ice on the street door for the house;
rust;
changing the appearance of the input structure.

These questions are best dealt with in detail.

Metal doors

Most apartment owners of multi-storey buildings choose metal structures. Such products are distinguished by high fire safety, and are also less susceptible to bad weather and mechanical damage.

However, you should get acquainted with the design features of such products, as well as the characteristics various models. If the door is made with high quality, it can protect the property of the owners of the apartment from theft. It is necessary to take care in advance of the possible prevention of freezing of the product.

Design

It is worth thinking more about choosing a warm front door for your apartment in terms of structural reliability. Strength characteristics are affected by many factors. Among them, manufacturing technology occupies a special place. It is better to choose doors that are made of steel sheet having a thickness of 1.5-2 mm. The thickness of the sheet is directly related to the rigidity and strength of the door.

Important! Inside the door there should be enough stiffeners to ensure the preservation of the geometry of the structure.

Schemes of stiffeners can be different:

transverse - when only horizontal elements are present;
longitudinal - with vertical ribs;
combined- as the name implies, both vertical and horizontal elements are installed in such doors.

Ribs arranged vertically are designed to resist twisting of the web. Due to this, the corners of the door cannot be bent. Horizontal ones are made to prevent the canvas from being squeezed or squeezed out of the box.

The best option is to purchase a door with combined ribs. This will completely protect the door from possible mechanical deformations.

Entrance doors to a private house can be equipped with a metal sheet not only on the outside, but also have a metal sheet on the other side. The structural elements are fastened to each other using a welding machine.

Provide elevated level security is possible only with the purchase of an armored door. Such models are produced using the technology of creating safes. Concrete is poured into the structure itself. This provides bulletproof product. Usually, entrance doors for a private house of this type are also equipped with special locking mechanisms of increased strength.

It is not recommended to buy a door made of metal sheet with a thickness of less than 1.2 mm. Often such products are sold under the brand name of Chinese production. Such tin can be cut with a regular knife.

The strength and reliability of the structure is also determined design features boxes. It is better if the box is made of steel 0.3-0.5 cm thick.

Additional elements for protection

In addition to a reliable and durable door frame, it is necessary to provide high protection against burglary due to the installation of reinforced hinges. They can have a different shape and be ball, safe, ordinary. Models with a support bearing are the most durable and efficient.

The design of the door affects the number of hinges. It is necessary to take into account its dimensions and material exterior finish, the amount of insulation. Even with small sizes doors must be equipped with at least 3 hinges. This will provide maximum protection. It is better if the loops are internal.

Metal entrance doors to a private house are equipped with pins that provide resistance when trying to remove the structure by force. Usually they are located at the end of the door. Such elements are able to fix the structure closed. Even with a successful attempt to cut the hinges and locks by an intruder, the door still will not open.

thermal insulation

In the harsh weather conditions of the Russian climate, special attention should be paid to reliable thermal insulation of the front door. If external decorative trim absent, frost on the metal sheet appears every winter. However, even in the case when the door is equipped with a double cladding, and there is a vestibule in front of the entrance to the apartment, the room is not sufficiently protected from the penetration of cold air.

In order for the temperature regime to be optimal, it is necessary to insulate the door with special materials. Usually use expanded polystyrene or mineral wool. Such materials have a low degree of thermal conductivity. To maximize thermal insulation, insulation should be placed in a special frame. When choosing an entrance door, be sure to clarify this.

Freezing of the door is excluded in several ways:

Installation of a cold vestibule. The second door, which will go directly into the heated room, must be made of metal-plastic. This will maximize the protection of the room from serious heat loss.
The cold door at the same time will not come into contact with warm air masses. This method of preventing freezing is more effective, therefore, it is used by many owners of apartments or individual houses.
The use of insulated entrance doors for a private house with thermal breaks. A special insert is placed in such products, which is made of polyamide. The material has many advantages to effectively prevent freezing of the structure. For example, if the air temperature is -25 degrees on the street side, the inside of the structure will have an indicator of + 10 degrees. Typically, these models of doors are quite expensive.
Installing an electrically heated door. Install along the contour of the structure heating cable. This prevents the formation of condensate. Electricity is consumed in the range of t 2 to 8 kW per day.

Regardless of the option chosen, it is imperative to equip the door with a double or triple insulation circuit. So cold air masses the road to the premises will be blocked.

Exterior finish

Before choosing a specific model of a street door, it is important to consider the features of the architectural style of the entrance. If it is in direct contact with the street, it should be lined with a material that is not afraid of temperature changes. It is also worth considering that the upholstery will be affected by various atmospheric phenomena and precipitation.

For entrance street doors, it is not recommended to use various chipboards as external upholstery. This rule also applies to PVC-coated products. Such products are not able to tolerate high humidity, they quickly become unusable under the influence of rain and snow, as well as high humidity.

Hammer painting will help to effectively protect the door from moisture. This type of coating is used for areas with a harsh climate.

If vinyl cladding is chosen, several features of the material should be taken into account. Such a coating does not have good frost resistance. After the temperature drops to -20 degrees, the coating becomes more brittle.

To give the door an exquisite appearance, you can choose waterproof shipboard panels as a facing material. They are usually made from species such as oak, pine, alder.

conclusions

Unambiguous answer, which door better fit for an apartment or a private house, does not exist. It is important to consider factors such as climatic conditions region, intensity of operation, architectural style of the entrance. You can buy a finished structure or insulate the door yourself. In the second case, you can save a lot.

To reduce the heat loss of the premises, a number of measures are taken, among which the main one is insulation doorway and canvases. The range of material requires a more thorough study of the varieties in order to select a more suitable product and create the most comfortable microclimate in the home.

When buying a door, it is necessary to specify what type of insulation is placed inside the canvas, whether it has soundproofing properties, which is important for apartment building.

standard type metal structure doors include the following:

Reinforced frame made of a profile pipe;

Rubber seal located along the inner contour;

An intermediate layer of a material with heat and sound insulation properties;

Interior finishing panel;

Stiffening ribs with vertical placement;

Door cavity filler;

fasteners;

External finishing panel;

Loop equipped with a support bearing;

Steel sheet (average thickness is 2-5 mm);

Rubber seal located along the outer contour;

Steel and decorative trim.

Having studied structural elements, you can competently ask questions to the seller regarding the heaters that fill the cavities of the canvases, and other important nodes. This will help you choose the best option for the entrance or interior door.

Types of insulation for doors

The materials that most often fill the cavities of the canvases:

Mineral wool has excellent sound and heat insulation, withstands temperature fluctuations without compromising performance. The environmentally friendly composition is absolutely safe for human health. Most often, basalt insulation is used in production, since it is not exposed to a humid environment. Shrinkage is considered the only drawback of the material. If there is a weak protection of the door from winds and frosts, then it is necessary to replace the mineral wool. It is not worth using the usual type of mineral insulator because of its hygroscopicity. Only basalt mats are moisture resistant.

If the door is supposed to be insulated mineral wool, you need to install additional stiffeners that will prevent shrinkage of the material. Additionally, it is recommended to glue the base to which it is planned to fix the cotton wool with glue.

Honeycomb filler is a cardboard structure with cells. The environmental friendliness of the material is supported affordable price. Sound and heat insulation qualities are also noted, but they are slightly inferior to mineral wool. Corrugated cardboard adequately tolerates temperature changes and a humid environment, which makes the material quite suitable for insulating the front door. The mesh construction provides additional rigidity to the web surface. And the main advantage is considered to be low weight, which does not give an extra load on the door frame and hinges. The disadvantages include: low moisture resistance and fragility.

Styrofoam is the most popular door insulation. The material has advantageous characteristics: moisture resistance, low thermal conductivity, long service life. It is easy to install, and the composition does not pose a danger to the health of the household. The pricing policy is also competitive. Light weight does not load the door structure. However, the heater also has disadvantages. These are combustibility and release of toxic substances when heated, as well as low noise absorption.

Polyurethane foam is less often used for door insulation due to the specifics of the layer application, which involves the use of equipment. The material is a liquid viscous substance. When sprayed, it produces monolithic coating, which excludes the penetration of drafts and cold air. High adhesion eliminates the installation of the frame and the use of any adhesive compositions. Polyurethane foam fills all the voids and cracks, which makes the canvas airtight. High humidity and temperature differences are not a problem for the material. The insulation gives the fabric additional rigidity. The disadvantages include only the price and specificity of installation.

Foam plates have sufficient sound and heat insulation to provide a comfortable microclimate in the home. The material is not subject to shrinkage, changes in properties due to temperature fluctuations and a humid environment. With all the advantages, it should be noted that in terms of thermal protection, the insulation loses to other types.

Features of door insulation

The selected material is installed in the web cavity. If, after dismantling the doors, they were not found, then it is necessary to make inside frame, on which the thermal protection will be fixed.

First, all overhead elements (accessories and decor) should be removed from the canvas, after which the door is laid on the desktop. From the inside, first around the perimeter they are stuffed wooden blocks. When choosing the thickness of the frame elements, the parameters of the door frame should be taken into account, otherwise the sheathed door simply will not close during installation. Further, the resulting perimeter is divided by wooden slats into cells, the size of which corresponds to the insulation.

AT recent times metal and plastic entrance doors have gained popularity, but wooden structures still do not go out of fashion. This is easy to explain, since the tree not only has high heat and sound insulation characteristics, but also looks beautiful. And if the entrance wooden door is additionally insulated and sheathed, then it will perfectly protect from the cold and decorate any home.

The device of the entrance wooden insulated door

Models designed for outdoor installation withstand temperature changes and retain their original characteristics and appearance throughout the entire service life. In addition to the fact that insulated wooden doors do not let heat through, thanks to modern processing technologies, it is ensured long term services of such structures.

The entrance insulated wooden door has high performance characteristics and beautiful appearance

The front door made of wood has the following advantages:

minimal heat loss - due to the weak thermal conductivity of wood and the presence of a layer of insulation in the house, the optimum temperature is maintained, saving money on paying for heating;
A wooden door with internal insulation can be made as a paneled door.
lack of condensate - there is no large temperature difference on the surface of the door. And the absence of moisture on the door leaf and on the wall allows you to increase their service life;
good sound insulation;
beautiful appearance.
A wooden front door can become a real decoration of a private house.

Insulated door structure

Modern technologies make it possible to create high-quality and reliable wooden doors. They are installed both at the entrance to the house and to the apartment. The insulated wooden door consists of the following elements:

frame - made of solid wood or wooden blocks;
frame wooden door can be assembled with your own hands, if you have experience working with wood material
insulation - applied on the outside or inside of the finished door, and sheathing is made on top of it decorative material. AT wooden houses the insulation on the door is sheathed with slats. There are factory options when a layer of insulation is placed inside the door. If the door is made frame independently, then the insulation spreads between sheets of chipboard or MDF;
The presence of different types of insulation of the front door allows you to choose the right method for each specific case.
sealant - fastened around the perimeter of the web or box, or in both places at once. This is done with glue, double-sided tape or furniture nails. The thickness of the seal must correspond to the gap between the box and the door leaf, therefore, in each case it is selected individually.
The seal ensures a snug fit of the leaf to the door frame

A small lunge is made on the door leaves to close the gap between the box and the canvas.

Different types of heat-insulating materials can be used to insulate a wooden door.

Production of entrance wooden doors with insulation

The ideal option is to buy a ready-made insulated door. However, the cost of such a design is quite high. But on the other hand, you can insulate your old one or independently make a new insulated entrance door.

door insulation material

First you need to figure out which heaters are used for wooden doors. These materials include:

corrugated cardboard (cellular cellulose) - consists of many honeycombs, fits inside door leaf. To achieve the desired thermal insulation qualities of the door, it will have to be laid in at least three layers. Corrugated cardboard does not have high performance, therefore, it is not suitable for insulating a street door to a house. But they can insulate the door to the entrance or to an apartment located not on the ground floor;
Corrugated cardboard is a simple and cheap material with poor insulating qualities.
Styrofoam (expanded polystyrene) is a lightweight and inexpensive material with good insulating characteristics. Disadvantages: absorbs moisture (condensate accumulates in it, the door freezes through), low fire safety, toxic substances are released during its combustion. Over time, gaps appear between the individual foam plates, heat loss through such a door increases;
If the front door is insulated with polystyrene foam, then it is better to use large pieces, rather than folding a mosaic of small ones.
mineral wool - poorly conducts heat, does not rot and does not burn. The cost is higher than that of foam. Wool is an ideal insulation for walls, facades or attics, but not very suitable for doors. Since when using the door, shocks occur, as a result of which the cotton wool settles and crumple;
To protect mineral wool from moisture, it is necessary to additionally use a waterproofing film
polyurethane - a material in the form of foam fills the voids of the door leaf well and after a while turns into a dense porous mass. Pros: does not burn, is not afraid of moisture and does not settle during the operation of the door. A layer of 25 mm thick polyurethane foam is enough to provide the same thermal protection as Brick wall 650 mm thick;
Polyurethane foam is an excellent material for insulating a wooden front door.
foam rubber - a kind of foamed polyurethane, produced in rolls or plates. Used for thermal insulation of a wooden door from the outside. Different types foam rubber differ in thickness and density. For sheathing the door leaf, sheets with a thickness of at least 30 mm are used. Narrow rollers are also made from this material. They are mounted around the perimeter of the door in the form of seals;
It is convenient to work with foam rubber: it is light, soft and pliable
isolon - on the one hand it has a foil coating that reflects heat into the room. The thickness of the isolon can be different;
Isolon is usually used to insulate the door from the outside
batting and felt - these materials were used before. Now they are practically not used for insulation of entrance doors, as they quickly lose their protective characteristics;
Batting and felt are now more often used in the manufacture of furniture, warm clothing and various interior items
genuine leather or artificial (leatherette) - auxiliary materials with which the door leaf is sheathed over the insulation. They are also an additional layer of thermal insulation;
For upholstery of the front door from the inside of the room, artificial or genuine leather is most often used.
rubber - also an auxiliary material, is used to create wide seals, with which the gaps between the box and the canvas are closed.

To insulate the door, you can use any of the described materials. It is only necessary to choose the right thickness and perform the installation with high quality. But the optimal insulation for this moment considered polyurethane.

How to insulate the entrance wooden door with your own hands

If you decide to insulate a wooden front door yourself, you first need to decide on the condition of the door leaf and frame. They must be of high quality and without damage. And also it is necessary to take into account that the insulated door will become heavier. Therefore, it is important that the hinges withstand the new weight.

Strengthening the door frame

First, the condition of the door frame is assessed. If it dangles, then you should additionally fix it.

Over time, the foam, with which the gap between the box and the wall was filled, collapses. If this happens, then it must be removed and the gaps filled with new mounting foam.

The geometry of the door jamb is then checked. If in some places the door rubs against the box, such a violation must be eliminated. To do this, either the hinges are tightened more tightly, or the door leaf is adjusted with a planer.

Installation of sealing elements

When choosing them, it is necessary to take into account the size of the gap between the canvas and door frame. It is important to measure the perimeter of the canvas correctly so as not to be mistaken with the length of the self-adhesive sealant, since it is produced in rolls.

To install the seal, it is enough to remove the protective film from it and stick it on the door and door frame

Sealing gaps with rollers

Usually, the rollers are made from the same material that is used for door upholstery: leather or leatherette.

Leather rollers are nailed either from the inside along the edges of the door jamb, or from the outside along the edges of the door itself: their installation is carried out with an additional overlap

The process of warming with rollers:

For better protection from the cold, the roller should protrude 2–3 cm beyond the door leaf or jamb.

Door lining with insulation

Although the process of door insulation requires some effort and knowledge, there is nothing complicated in it, everything can be done independently. For this you will need:

insulation;
upholstery;
a hammer;
measuring instruments;
stationery knife.

For this method of door trim, any soft insulation is suitable: foam rubber, mineral wool, polyurethane, isolon. The sequence of work is as follows:

The canvas is removed from the hinges and placed on a flat surface.
Measure the dimensions of the door leaf.
To determine the size of the insulation and upholstery, it is necessary to correctly measure the door leaf
Determine the size of the insulation and upholstery. After measuring the door leaf, the obtained dimensions are transferred to the insulation, 1 cm is taken from each side. For upholstery, on the contrary, 3-5 cm are added to the dimensions of the door.
The hardware is removed from the door so that it does not interfere.
A layer of insulation is laid on the door, fixing it. Cover with upholstery on top, its edges are folded under the insulation.
It is important to fix the insulation well so that it does not move during operation and does not form voids.
Using nails, fix the upholstery around the perimeter of the door leaf. During this, it is necessary to constantly pull the material tightly, otherwise wrinkles may form. Fastening is best done from the middle of the door to the edges.
To fix the upholstery, decorative nails with wide hats are used so that the skin in these places is not damaged.
Carefully make holes for the handles, peephole and lock. After that, fix all the details in their places.
Rollers are nailed.
Decorate the door with a decorative pattern, which also serves as an additional fixation of the insulation. To do this, a certain pattern is applied to the upholstery with chalk, decorative nails are nailed along its contours. Between these nails, you can stretch a fishing line or thin copper wire.
When creating a decorative pattern, you need to monitor the uniform tension of the fishing line between the nails.
Hang the door on hinges.

Foam insulation

Here the sequence of work will be slightly different from the previous version. With the help of polystyrene foam, there are two ways to insulate a wooden door:

Features of installation and operation of the door

Installation of an insulated wooden entrance door in a wall opening is carried out in the same sequence as any other. You can cope with this task yourself, but first you need to prepare tools and materials:

perforator;
Bulgarian;
electric drill;
a hammer;
roulette;
building level;
screwdriver or a set of screwdrivers;
anchor bolts;
mounting foam;
wooden wedges.

The door installation process consists of the following steps:

Preparing the doorway - if hanging old door, then it must be dismantled together with the box. After that, the opening is cleaned from old plaster, polyurethane foam. If voids have formed, they are closed cement mortar. With the help of a grinder and a perforator, the protruding parts of the opening are removed.
The edges of the opening are made even: its size must correspond to the size of the door frame
Installation of the frame - the door frame is installed in the prepared opening and is aligned in the horizontal and vertical direction with the help of wooden wedges.
The wedges are evenly distributed around the perimeter of the box, with their help they fix the position of the door frame in the opening
Checking the installation - the building level checks the correct installation of the box. Be sure to control the size of the diagonals: they must be equal.
With help building level check the correct installation of the door frame: it should not be skewed, otherwise the door will not close
Fixing the box - holes are drilled in the box with an electric drill through which it is attached to the opening with anchor bolts.
The upper parts of the anchor bolts expand inside the opening during tightening, so this fastening becomes more reliable.
Installing the canvas - the door is hung on the hinges, its free play is checked. Three hinges are used for the insulated front door.
Sealing the structure - the gap between the box and the wall is filled with mounting foam, while the canvas must be in the closed state. Then platbands are attached around the box.
The mounting foam must be squeezed out a little, so that after it swells, large protruding pieces do not stick out

Operation features

When buying an entrance door, it is important to pay attention to what materials it is made of and how high quality it is. And if the door is installed correctly, then during its operation it remains to adhere to the following recommendations:

The main functionality of outdoor door structures- ensuring the safety of the home and the safety of property. In Russian conditions, this is not enough. In the conditions of the Russian climate, especially in Siberia, there are cases of freezing. This reduces the service life and leads to inconvenience.

The insulated entrance street door reduces energy costs during the cold period by 30%. Taking into account the average life of the door - up to 10 years, this gives significant savings for the period of operation.

About what should be the entrance street insulated door will be discussed in this article.

Currently, manufacturers offer three types of entrance doors:

steel metal;
wooden;
plastic doors.

The model is considered insulated if it has a double sealing circuit and a heater. Naturally, this is not enough if you choose insulated front doors for a private house. Especially if the place of its operation is Siberia, the Far North or Far East, and foam rubber or mineral wool is chosen as a heater. There is no uniform GOST for insulated doors of all types. Therefore, many manufacturers use innovative solutions and their own developments, introducing details and insulation elements into the design.

When choosing an insulated model, you should pay attention to the following characteristics:

number of sealing circuits. They protect against the penetration of cold air and the occurrence of drafts. The more sealing contours a door has, the more airtight it is.
web thickness. More massive products give off heat more slowly. A massive door is not only additional security, but also a guarantee that it will not freeze in the winter.
Insulation material. In some models of metal doors, foam rubber or mineral wool is used. The thermal insulation properties of these materials are not great. Naturally, they are not suitable for use as an insulated front door for a private house. Although in the characteristics you can find a link to the insulated version. The price of such an insulated street entrance door is low. In modern designs, foam, foamed polyurethane are used. For expensive and exclusive products, wood fiber is used.
thickness of the insulation layer. The thicker the layer, the higher the level of thermal insulation of the room. For massive doors, the thickness of the insulation layer is usually higher than for smaller counterparts.
The number of layers of insulation.
The presence of innovative technologies and design developments: double canvas, the use of thermal break technology, the absence of contiguous metal surfaces etc.

Insulated metal doors

Metal doors can have an internal and external wood-like leaf

Steel doors are manufactured in accordance with GOST 31 173-2003 “Steel door blocks. Specifications". This is the most common segment on the market. A metal door allows you to provide maximum protection for your home from breaking and unauthorized entry. But the material has a high heat transfer. Therefore, most of the innovative technologies have found their application in the creation of street entrance metal insulated doors.

Advantages:

almost every model has a layer of insulation, you can find designs with a double and even triple layer;
not exposed to moisture, so that the insulation retains its properties for a long time;
do not have cracks and effectively prevent the occurrence of drafts;
high degree of sealing. Metal models do not warp. This ensures a constant gap size between the door frame and the leaf, which is hermetically sealed by two or more sealing circuits;
thanks to the massiveness and weight metal door the thickness of the filler layer can reach 60 mm or more.
some models have an outer and inner fabric, which reduces heat transfer;
the use of thermal break technology allows to reduce the heat transfer rate. In models with two door leafs, the degree of heat transfer is the same as that of wooden counterparts.

The design of a modern insulated door with a thermal break

Wooden insulated doors have low heat transfer. Naturally, this applies to models made of solid wood and treated with special compounds. Some manufacturers make products modern technologies from special panels processed mineral compositions and tannins. They are not deformed, not subject to moisture and rotting. Special coating protects against cracking. The service life of such structures reaches twenty years. To become the owner of such a door is not a cheap pleasure.

Advantages

Weight and weight are lower than those of metal counterparts.
High level of thermal insulation.
The ability to independently correct the shortcomings of thermal insulation.
Frost resistance.

Insulated plastic doors

They are made according to Canadian or domestic technology from sandwich panels and have a prefabricated structure. Multilayer structure plastic doors provides sufficient thermal protection of the room. A big disadvantage of such products is the lack of the possibility of introducing innovations. Plastic as a material is not subject to impregnation and the effects of mineral and organic compounds. It has less room for performance improvement than steel with the addition of various alloys. Insulated plastic doors double circuit seals and polyurethane foam filler are widely used for installation at the entrance to an apartment in Central Russia, but they are unlikely to replace metal or wooden construction in a private house.

Market trends

The modern domestic market is on the path of improving security and protection against unauthorized entry. High characteristics of burglar resistance have metal input street doors. Consequently, a large number of insulated models are made of steel.

New models in insulated design are made taking into account the following trends:

The use of quality and modern materials as a heater.

For example, thermal insulation properties such material as isolon is ten times higher than that of mineral wool or foam rubber.

The use of several types of insulation and, accordingly, an increase in the number of layers.
Introduction of new technologies. For example, products made using thermal break technology do not have external and internal metal parts in contact. This allows you to achieve the same thermal insulation characteristics as those of wooden counterparts.
Increase in the number of sealing circuits and the use of innovative sealing materials.

Models of foreign and domestic manufacturers are presented on the domestic market. They all position themselves differently in the market.

Stardis doors

Manufacturers such as Zenith, Granite operate in the inexpensive segment of the market and provide their customers with the best offer in terms of price-quality ratio. The insulated door Zenith, Stardis or Granite will have two sealing loops and one layer of inexpensive filler. Doors of insulated metal brands Forpost or Condor have a higher price. Models of these manufacturers have high-quality insulation and an additional sealing circuit.

Manufacturers such as Gerda, Fortis, Superlock position themselves as manufacturers of burglar-resistant structures. Burglary-resistant models have quality materials and accessories, several sealing circuits.

Door manufacturer Imperial offers products with quality finishes made of natural materials, paying little attention to the thermal insulation of their products. Excellent results are shown by insulated Thermo and Torex models, made using innovative technologies. With the advent of thermal break technology universal doors Thermo became the market leader.

Conclusion

The range of products on the market is quite wide and varied. This allows the user to make right choice for all occasions. A universal option for operation in the cold climate of Russia is to purchase insulated entrance doors from a domestic manufacturer.

The temperature regime inside the house depends on many factors. Entrance doors often let in cold air, as they have low thermal insulation. Manufacturers of these structures try to minimize this factor as much as possible. Today, there are several types of such systems on the market, among which insulated wooden entrance doors should be highlighted. Not only do they hold heat well, but they are also durable.

What are they for?

Entrance doors are the cause of drafts and the penetration of cold air into the premises. This leads to an increase in heating costs, and also leads to the appearance of mold. Very often, similar structures were installed on the balcony, where the same problems arose.

The solution to this problem is insulated door leafs. Outdoor models perfectly withstand temperature changes in winter, and also perfectly retain their original parameters. Therefore, many owners often change old products for these products.

A warm door allows you to solve several problems:

The product minimizes heat loss. This makes it possible to maintain the optimal temperature inside the house and at the same time reduce the amount of fuel for heating it. This is achieved through several layers of insulation, which eliminates almost all gaps.
The door leaf has high soundproofing parameters. External sounds and smells will not penetrate into the house. This will create an optimal microclimate inside.
A warm door does not allow condensation to form on its surface. This is achieved due to the fact that there is no temperature difference. Water does not destroy the surface of the canvas and walls, where it settles.

This type of door can be used both in a private and multi-storey building. High-quality models are made from durable wood species, which are distinguished by durability and unique decorative characteristics.

Structure

Insulated wooden doors have been popular for a very long time. They perfectly withstand frosts, and also resist temperature extremes. One of the disadvantages of this product is that the wood must be constantly maintained to prevent large cracks from occurring.

This design consists of several main layers:

frame. It is made from solid wood or from bars of a certain thickness, which are sheathed with MDF or chipboard sheets. The first version of the door leaf is different high quality and is the main one in the market.
sealant. It is attached over wooden canvas- using glue or furniture nails. To add beauty from above, all this can be sheathed with a decorative fabric. All these materials are selected for the specific climatic conditions of the zone where the house is located. This minimizes their destruction and ensures a long service life.

Please note that the insulation can be located both on the outer or inner side, and cover both parts. The latter option is practiced quite rarely, because doors that are well insulated on one side can provide the desired effect.

Today, there are door models in which the seal is located inside a wooden box. This structure provides better insulation, and also retains unique design wood. The cost of such products is much higher than the price of structures that are upholstered with insulation on top.

To minimize heat loss, the sashes are made with a slight lunge. It is intended to close the gaps between the box and the canvas. Many options are complemented by special seals that prevent the occurrence of holes in the closed state of the doors.

To make the door original, decorative overlays are placed on top of the finish.

They are made from sheets of MDF or veneer of various tree species (oak, beech, hornbeam, pear, walnut, and so on). Their shape can be different, which allows you to add volume and beauty. Some types of insulated doors can be supplemented with inserted glass, but such designs are already much more expensive than conventional counterparts.

What is the best way to insulate?

Today, wooden doors are used in many private houses or apartments, but they do not have sufficient thermal insulation characteristics. For insulation of a balcony system or canvas in country house You can use several types of materials, their set:

Foam rubber. It is a foamed polyurethane that perfectly retains heat. Today, there are several types of foam rubber on the market, differing in density and thickness.

For upholstery of doors, a set of material with a thickness of at least 30 mm should be used. If the winters are cold, then this parameter can be increased. Rollers are also made from it, which are installed around the perimeter of the canvas to prevent the movement of cold air.

Izolon. The best option will be an isolated variety of this product. It is covered with foil on one side, which more carefully reflects heat. The thickness of the isolon sheets can also be different.

Please note that thermal insulation characteristics of this product is much higher than foam rubber. This makes it possible to achieve desired results when using thinner sheets.

Batting and felt. They have been used as insulators in the past. Today they are becoming less and less common, as they quickly become caked and lose their original parameters. Sometimes they are used as an additional layer - in multilayer insulation systems.
Mineral wool. This material perfectly retains heat, and also does not burn and does not support combustion. But the sheets of cotton wool are of considerable thickness, which will affect the external dimensions of the door leaf. This material can accumulate moisture, which leads to its rapid caking. To eliminate this factor, mineral wool is placed between layers of insulating film.
Polyfoam (foam). One of the cheapest and most affordable heaters. This substance retains heat well, but can also accumulate moisture. Therefore, it should be insulated, as is the case with mineral wool.

One of the disadvantages of this material is that it burns beautifully. At the same time, he also highlights harmful substances into the air, which have a very negative effect on the human body. There are several types of foam on the market, which allows you to choose it both in thickness and density.

Textile. This material is auxiliary, as it is used for decorative sheathing of previously considered heaters. Today, both dermatin and genuine leather are used for such purposes. They are another additional layer that increases the level of thermal insulation.
Rubber. This material is used as an auxiliary. Seals are made from it, which are attached to the door leaf. This eliminates the occurrence of drafts that form in the cracks. Today on the market you can find many types of seals that differ in shape and installation method.

Almost any of these materials can be used in a rural house. The main thing is to choose the right layer thickness, which will provide the optimal level of thermal insulation.

How to do it right?

Warming a wooden door can be done with your own hands, it's quite simple. It is important to understand at the same time that ready-made structures can only be sheathed on the outside of the canvas. The algorithm for implementing this procedure consists of several successive steps:

Removing the door leaf. This will greatly simplify its upholstery - both from the inside and outside (relative to the room).
Fastening the heat insulator to the surface of the canvas. The material is fixed in several ways, it depends on the material used.
Sheathing of sheets with decorative fabric. It not only decorates the surface, but also additionally hold the heat insulator.
Laying seals. Such materials are used if it is necessary to provide complete thermal insulation. To do this, seals are attached around the entire perimeter of the door leaf. It is important that when closing they are tightly connected, excluding the occurrence of cracks.

Some experts recommend installing rollers with seals. These designs are small foam cylinders that are wrapped in the same fabric as the door. They are attached to the box in such a way that they close the gaps. They are located on the side in which the door does not open.

As for the door upholstery, it can be done in several ways, which depend on the chosen insulation:

Sheathing. This is the easiest way, it is quite easy to handle such work yourself. For this, foam rubber and leatherette are often used. Foam rubber is placed on the surface of the canvas, and then covered with upholstery fabric. After that, the material is nailed to the tree with decorative nails. Attachment points are selected individually, the main thing is that the fabric is held on the surface of the doors. Please note that this technology can be used not only with foam rubber, but also with isolon, mineral wool. It is important here to select high-quality fabric upholstery that will hold this system.

Frame finish. So you can insulate with almost all types of heaters. The technology involves the construction of a rigid frame around the perimeter of the canvas. As materials, wooden planks of a certain thickness are used. They are screwed to the door with screws or nailed. To ensure the optimal level of support for the insulation, several horizontal partitions from the same bars should be nailed.
